Issues hosting multiple domains

[loza0269]

When you launch the gophish docker as a daemon you access your portal by going to your machine IP. Although, my understanding is that docker containers run as their own image and environment for a lack of a better word, but to access the portal you still put the host machine IP. Is there an IP assigned to the docker image?

Our goal is to create docker images with domain names attached to them that we can host all on one machine. Is it possible to either determine an IP for the docker container and point my DNS at that or is there another method the community might know of?

If this is not possible to begin with, is there any workaround you can think of?

I appreciate your time!
Thank you
